I am 8 days late for my period, and when I tested, I saw two lines, one dark and one light. I had an ultrasound, and the doctor said my endometrium is thick but no gestational sac was visible, possibly because the embryo is still implanting. So, I would like to ask if being late for my period, having a thick endometrium, and not seeing the gestational sac means I am pregnant?

The endometrium plays a crucial role in conception and pregnancy in women. Each month, under the influence of female sex hormones, the endometrial lining thickens in preparation to receive a fertilized egg for implantation. If fertilization does not occur, the endometrial lining sheds and menstruation follows. However, in some cases, due to hormonal imbalances or other factors, the endometrium may thicken abnormally, making it difficult for the embryo to implant, which can lead to a miscarriage. Let’s explore in more detail what a thickened endometrium means in the following article.
